GEORGE lVASHINGTON lVALTON, OF SPARTA, TEXAS.

WOOD-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 448,388, dated MarchI7, 1891.

Application filed June 28, 1890. Serial No. 357,113. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE WASHINGTON XVALTON, a citizen of the UnitedStates, residing at Sparta, in the county of Bell and State of Texas,have invented a new and useful \Vood-lVorkin g Machine, of which thefollowing is a specification.

This invention relates to wood-workin g machines; and the object of theinvention is to eifect improvements in devices of the same generalcharacter heretofore existing.

To this end the invention consists in the construction hereinafter morefully described and as illustrated in the drawings, in which Figure 1 isa plan view of this machine. Fig. 2 is a section on the line 2 2 ofFig. 1. Fig. 3 is a perspective detail of the feeding mechanism, andFig. 4c is a section on the line a 4 of Fig. 1.

Referring to the said drawings, the letter F designates a suitable framework, within which the hereinafter-described mechanism is supported andj ournaled in any suitable manner, and D is the main driving-wheel,preferably operated by a crank, as shown. This drive-wheel is keyed on ashaft S, which is cranked near the said wheel, and on said crank ismounted a feed-rod R, which extends through the frame-work and serves apurpose to be more fully set forth presently.

B is a belt, which passes over the drivewheel D, over guide-rollers G,and along the frame-work, out the front end thereof, and over thecutter. On the upper side of the frame there is but a singleguide-roller; but on the lower side thereof there are two, and betweenthese there is loosely mounted 011 the said belt 13 a frame f, whichcarries a weight XV, adapted to impart a sufficient tension to the beltto keep the same tight at all times.

K is a bar slotted longitudinally and provided with teeth in its slot,and P is a pawl connected to the frame and normally engaging said teethto keep the bar distended. The front end of the feed-rod R has a lateraltongue 0', which projects through the slot under the pawl P, and alsoengages the teeth therein, and as the crank reciprocates this rod thebar K is fed forward step by step, one notch at each revolution of theshaft, and the pawl 1? holds it against a retrograde movement. The rod Rhas a loose bearing on the crank of the main shaft, so that it can movelaterally, whereby its tongue 0" may be disengaged from the teeth, andin the frame F, where this rod passes therethrough, is a pin N, whichwhen in position bears against the side of the tongue and holds it inengagement with the teeth, but when withdrawn permits the tongue to bemoved laterally and disengaged. When the tongue '2" is in positionbeneath the tip of the pawl P and said tongue is raised, it will alsolift the pawl, because it stands beneath it, as above described.

The slotted bar K carries side wings 7c,wh ich guide it in its movementwhere it passes through the'outer end of the frame F, and in the latteris formed a hole of the proper shape and size to permit the free passageof the bar and its wings. The wings 7c terminate just short of the outerend of the bar K, and said end is provided with a transverse hole.Through this hole is j ournaled a pin or bolt 72, upon the opposite endsof which are mounted the heads H, their inner ends next the two sides ofthe bar K being preferably reduced, as at b, to permit the band B tomove there in. Vithin the two heads H and against the ends thereof aresecured the knives or cutters proper C in any preferred manner.

The operation of this device is as follows: The head being broughtagainst the material or article it is desired to cut or rout and theslotted bar K being retracted, a weight is attached to the framefand thewheel D is revolved. By the belt B and relative sizes of the drive-wheeland cutter one revolution of theformer causes the latter to revolve anumber of times or very rapidly when the drivewheel D is turned slowly.At each single revolution of the drive-wheel-that is to say, once inabout every ten to twenty revolutions of the cutter-the bar K is fedforward by the rod R the distance of one tooth, and thus the cutter isgradually embedded in the material or article being operated upon at thesame time that it is rotated at a high rate of speed. To withdraw thecutter from the hole thus formed, the Whole frame can be retracted, orthe tongue r of the rod R can be raised and the bar K moved to the rear.

Considerable departure can be made from the details of constructionabove described without altering the principle of my invention.

What I claim is 1. In a wood-routing tool, the combination, with thetoothed bar, the cutter journaled in the front end thereof, a pawlengaging the teeth thereof, and a feed-rod also engaging said teeth, ofa main crank-shaft, upon the crank of which the other end of saidfeed-rod is mounted, a drive-wheel 011 said shaft, a belt passing oversaid d rive-wheel and cutter, and a belt-tightener thereon,substantially as described.

2. In a wood-routing-tool, the combination, with the toothed bar, thecutter jonrnaled in the front end thereof, a pawl engaging the teeththereof, and a feed-rod also engaging said teeth, of means,substantially as described, for imparting rotary motion to the cutterand reciprocatory motion to the feed rod, as and for the purpose setforth.

3. In a wood-routing tool, the combination, with the frame-work having asingle guideroller at the top and two guide-rollers at the bottomthereof, a longitudinally-moving cutter-bar, a cutter journaled in theouter end thereof, and means, substantially as described,for feedingsaid bar intermittently forward, of a main shaft journaled in saidframe, a drive-wheel thereon, a belt passing over said drive-wheel andcutter, the sides of the belt passing intermediately beneath the upperguide-wheel and above the two lower guide-wheels, a weight-frame havinga roller supported on said belt between said lower guide-wheels, and aweight attached to said Weight-frame, the whole operating substantiallyas and for the purpose set forth.

4. In a wood-routing tool, the combination, with the frame-work F, theslotted cutter-bar K, sliding therein and having teeth within its slot,the cutter journaled in the outer end thereof, and means, substantiallyas described, for rotating said cutter, of the pawl P, connected to theframe and engaging said teeth, the reciprocating feed-rod R, slidingthrough said frame, and the tongue 0" on the forward end of said rod,engaging said teeth beneath the tip of the pawl P, as and for thepurpose set forth.

5. In a Wood-routing'tool, the combination, with the frame-Work F, thetoothed cutterbar K, the cutter j ournaled in the outer end thereof, andmeans, substantially as described, for rotating said cutter, of the pawlP, connected to the frame and engaging said teeth, the feed-rod R,reciprocating longitudinally through a slot in said frame, the tongue 0'on the forward end of said rod, normally engaging said teeth beneath thetip of the pawl P, and the pin N, removably inserted through said slotin the frame and holding the tongue of the feed-rod normally inengagement with the teeth, as and for the purpose set forth.

6. In a Wood-routing tool, the combination, with the cutter-bar K,having lateral guidingwings 70 extending nearly to its outer end, a bolth, journaled through said outer end, and a frame-work F, supporting saidcutter-bar, of the heads H, mounted upon the opposite ends of said boltand having reduced inner ends I), said heads projecting beyond saidwings, the belt B, leading from a suitable source of power through saidframe-work F over said reduced inner ends of the heads, and the cutters0, carried by said heads, the whole constructed and arrangedsubstantially as and for the purpose hereinbefore set forth.

In testimony that I claim the foregoing as myown I have hereto affixedmy signature in presence of two witnesses.

GEORGE WASHINGTON WALTON.
